ABSTRACT
Objective To investigate the clinical characteristics of digestive system cancer during pregnancy and its influence on mother and fetus.Methods Clinical data of 12 pregnant women accompanied with digestive system cancer obtained from the follow-up record of cancer patients between July 2007 and January 2016 in Daqiao Community Health Service Center of Yangpu District,Shanghai,were retrospectively analyzed.Results Delayed treatment,missed diagnosis and misdiagnosis were found in ten of the 12 cases.Eleven cases underwent B-type ultrasound as an early imaging screening method.Eleven patients had advanced cancer,but only two of them were eligible for radical surgery.Five patients could be treated with anti-tumor therapy.Eleven of the 12 patients died within two years after diagnosis,and only one survived over five years.Eight of the twelve embryos or fetuses died and four neonates survived.Conclusions Digestive system cancer during pregnancy has an insidious onset,and the rates of missed diagnosis and misdiagnosis are high,with advanced disease stage at diagnosis and poor prognosis.Knowledge of the digestive system cancer during pregnancy and early diagnosis and treatment capacity should be enhanced so as to reduce the damage to both the pregnant woman and fetus.
